my brake light stay on on my dash iv chcked almost everything electrical, brakes, fluid e brake and brake light switch and everything is good does anybody have any other sugestions the truck is a 90 1500
The 90 has rear ABS brakes. More than likely sensor issue. It was not as critical on a 90 when they fail. (Some people disconnect them)
But I would put effort in it IMO to repair properly for piece of mind.
i found the problem its the combo valve that screws into the master cylinder and hooks into my rwal wiring harness the previous owners of the truck had it unpluged now correct me if im wrong but since thats the problem doesnt that mean its saying my front and rear brake pressure is diffrent if so couldnt i just bleed my brakes does this make sense
